thanks as ever Jim but looking to remove and fit bias box, was just seeing if the servo was common with 'owt else and therefore a bolt on option as opposed to boshing extra holes and getting the welder out

was juts being lazy really, will remove mine and check bolt hole PCD

Cant find any pictures - but I found an off the shelf generic wilwood bias box that bolts on with just a bit of drilling and a couple of clevis pins. Got it second hand off ebay I'm afraid so dont know part nos etc. One of this winters mods.
